  However, since a general factory drain pipe is more likely to deposit scales and dust and collect water than a household drain pipe, it is necessary to drain water before vacuum cleaning or the like. For this reason, in the drainage pipe with a cleaning port of patent documents 1 thru | or 4, the drainage port must be provided separately from the cleaning port, and there existed a subject that manufacturing cost increased.

  The present invention has been made paying attention to such a problem, and an object of the present invention is to provide a drain pipe with a cleaning port capable of reducing the manufacturing cost.

  In order to achieve the above object, a drain pipe with a cleaning port according to the present invention is a drain pipe with a cleaning port attached to a drain pipe, and includes a main pipe, a branch pipe, a lid, and two joint members, The branch pipe communicates with the main pipe and protrudes from a side surface of the branch pipe, and the lid is detachably provided to close the opening of the branch pipe, and each joint member connects both ends of the main pipe to the end of the drain pipe. It is characterized in that it is provided so as to be able to rotate about its central axis while supporting the main pipe when it is loosened.

  The drainage pipe with a cleaning port according to the present invention is used by being attached to a drainage pipe constructed almost horizontally. The drainage pipe with a cleaning port according to the present invention is used by connecting both ends of the main pipe to the end of the drainage pipe by each joint member. Usually, the branch pipe is arranged on the upper side of the main pipe and the main pipe is connected to the drain pipe so that dust or the like does not collect inside the branch pipe. When draining water, each joint member is loosened, and the main pipe is rotated around its central axis so that the branch pipe is disposed below the main pipe. At this time, since the main pipe can be rotated while being supported by each joint member, it is not necessary to support the main pipe by hand so that the main pipe is not dropped, and damage due to dropping can be prevented and rotation can be facilitated. In this state, if the lid is removed, water can be drained from the opening. After draining water, the opening is closed with a lid, the main pipe is rotated so that the branch pipe is arranged on the upper side of the main pipe, and each joint member is tightened.

  When cleaning the drain pipe, remove the lid with the branch pipe placed above the main pipe. Cleaning can be performed by inserting a hose, a suction nozzle, or the like into the inside from the opening of the branch pipe. Thus, the drainage pipe with a cleaning port according to the present invention has a single opening for cleaning and draining by directing the opening of the branch pipe downward when draining and directing the opening upward when cleaning. Can also serve. For this reason, it is not necessary to provide a cleaning port and a drain port separately, and manufacturing cost can be reduced. Moreover, since the direction of a branch pipe can be easily changed by loosening each joint member and rotating the main pipe, workability is good.

  In the drain pipe with a cleaning port according to the present invention, the main pipe and the branch pipe are preferably made of a transparent material. In this configuration, it is possible to see from the outside the scale, dust, water, and the like in the main and branch pipes. For this reason, it is easy to determine whether cleaning or draining is necessary, and maintenance is easy. Moreover, cleaning and draining can be advanced while confirming the situation in the main pipe and the branch pipe from the outside.

As shown in FIG. 1, the drain pipe 10 with a cleaning port includes a main pipe 11, a branch pipe 12, a lid 13, and two joint members 14.

The main pipe 11 is made of a transparent and hard vinyl chloride resin.
The branch pipe 12 is made of a transparent and hard vinyl chloride resin having the same diameter as the main pipe 11. One end of the branch pipe 12 is connected to the side surface of the main pipe 11 so as to communicate with the main pipe 11. The branch pipe 12 has an opening 12 a at the other end, and is provided so as to protrude obliquely from the side surface of the main pipe 11 so that the opening 12 a faces one end side of the main pipe 11. The branch pipe 12 has a reinforcing member 15 made of hard vinyl chloride resin along the outer surface of the other end. The reinforcing member 15 protrudes from the opening 12 a along the outer surface of the branch pipe 12 and is fixed to the branch pipe 12. The reinforcing member 15 has a female screw on the inner periphery of the portion protruding from the opening 12a. In one example, the acute angle formed by the side surface of the main pipe 11 and the side surface of the branch pipe 12 is about 45 degrees.

  The lid 13 has a larger diameter than the opening 12 a of the branch pipe 12. The lid 13 has a male screw that engages with a female screw of the reinforcing member 15 of the branch pipe 12 on one surface, and a knob 13a on the other surface. The lid 13 is detachably provided on the branch pipe 12 so as to close the opening 12a.

  As shown in FIG. 2, each joint member 14 is formed of a screw-type drain pipe joint (for example, a trade name “Prefab Joint” (manufactured by Asahi Organic Materials Co., Ltd.)). Each joint member 14 includes a joint body 16, a body cap 17, and a cap nut 18. The joint body 16 has a cylindrical shape and is formed so that the inner diameter on one end side coincides with the outer diameter of the main pipe 11 and the inner diameter on the other end side is smaller than the outer diameter of the main pipe 11. . The joint body 16 has a flange portion 16a on the other end side, and has a male screw portion 16b along the outer periphery thereof. A rubber O-ring 16c is attached to the joint body 16 along the opening surface on the other end side.

  The body cap 17 has a cylindrical shape, and the inner diameter is changed so that the inner diameter on one end side matches the outer diameter of the drain pipe, and the inner diameter on the other end side becomes smaller than the outer diameter of the drain pipe. . The body cap 17 has a flange portion 17a having the same outer diameter as the flange portion 16a of the joint body 16 on the other end side.

  The cap nut 18 has a cylindrical shape, the inner diameter on one end side matches the outer diameter of the flange portion 16 a of the joint body 16 and the flange portion 17 a of the body cap 17, and the inner diameter on the other end side is the outer diameter of the body cap 17. The inner diameter is changed so as to be slightly larger and smaller than the outer diameter of the flange portion 17a. The cap nut 18 has a female screw portion 18a that is screwed into the male screw portion 16b of the joint body 16 along the inner circumference on one end side.

  Each joint member 14 fits the flange part 16a of the joint main body 16 and the flange part 17a of the body cap 17 closely, inserts the body cap 17 from one end side of the cap nut 18, and the male thread part 16b of the joint main body 16 The cap nut 18 is assembled by screwing with the female screw portion 18a. At this time, the O-ring 16 c of the joint body 16 can prevent water leakage from the joint portion between the joint body 16 and the body cap 17. Each joint member 14 has an end portion of the main pipe 11 inserted into one end side of the joint body 16 and is fixed by an adhesive. Moreover, the edge part of the drain pipe 1 is inserted in the one end side of the body cap 17, and it fixes with an adhesive agent. In this way, each joint member 14 is configured such that both ends of the main pipe 11 are detachably connected to the end of the drain pipe 1 and can be rotated around its central axis while supporting the main pipe 11 when the cap nut 18 is loosened. ing.

Next, the operation will be described.
As shown in FIG. 3, the drain pipe 10 with the cleaning port is used by being attached to the drain pipe 1 that is constructed substantially horizontally.

At this time, as shown in FIG. 3A, the branch pipe 12 is arranged above the main pipe 11 so that the wastewater does not enter the branch pipe 12 and the flow is disturbed or dust is not collected inside the branch pipe 12. The main pipe 11 is connected to the drain pipe 1 with the opening 12a facing upstream. The branch pipe 12 may be used as a drain for removing dust by disposing the branch pipe 12 below the main pipe 11 and connecting the main pipe 11 to the drain pipe 1 with the opening 12a facing downstream. .

  When draining water, the cap nut 18 of each joint member 14 is loosened, and the main pipe 11 is centered on its central axis so that the branch pipe 12 is disposed below the main pipe 11 as shown in FIG. Rotate. At this time, since the main pipe 11 can be rotated while being supported by each joint member 14, it is not necessary to support the main pipe 11 by hand so as not to drop, and damage due to dropping can be prevented and rotation can be facilitated. If the lid 13 is removed in this state, water can be drained from the opening 12a. After draining, the lid 13 closes the opening 12a, and as shown in FIG. 3A, the main pipe 11 is rotated so that the branch pipe 12 is arranged on the upper side of the main pipe 11, and the cap nut 18 of each joint member 14 is placed. Tighten.

  When cleaning the inside of the drain pipe 1, the lid 13 is removed with the branch pipe 12 disposed above the main pipe 11. Cleaning can be performed by inserting a hose, a suction nozzle, or the like into the inside from the opening 12a of the branch pipe 12. As described above, the drain pipe 10 with the cleaning port is configured so that the opening 12a of the branch pipe 12 faces downward when draining, and the opening 12a faces upward when cleaning, so that cleaning and draining can be performed with one opening 12a. It can also serve as. For this reason, it is not necessary to provide a cleaning port and a drain port separately, and manufacturing cost can be reduced. Moreover, since the direction of the branch pipe 12 can be easily changed by loosening the cap nut 18 of each joint member 14 and rotating the main pipe 11, workability is good. In addition, since the drain pipe 1 is naturally flowing and water pressure is not applied, even when the cap nut 18 of each joint member 14 is loosened and the main pipe 11 is rotated, there is no water leakage from each joint member 14.

  Since the main pipe 11 and the branch pipe 12 are made of a transparent material, the drain pipe 10 with the cleaning port can be seen from the outside where the scale, dust, water, etc. in the main pipe 11 and the branch pipe 12 are accumulated. it can. For this reason, it is easy to judge whether cleaning or draining is necessary, and maintenance is easy. Moreover, cleaning and draining can be performed while confirming the situation in the main pipe 11 and the branch pipe 12 from the outside.

  In addition, since each joint member 14 removably connects both ends of the main pipe 11 to the end of the drain pipe 1, dust that cannot be removed by cleaning from the opening 12 a can be removed and removed. The maintenance of the pipe 1 is easy. Further, when the main pipe 11 or the branch pipe 12 is broken, the main pipe 11 can be removed and repaired or replaced easily.

  In addition, as shown in FIG. 3, the drain pipe 10 with a cleaning port may be used by connecting a plurality of drain pipes with a predetermined interval. Since the drain pipe 10 with the cleaning port connects the opening 12a of the branch pipe 12 toward the upstream side, cleaning of the downstream side of the branch pipe 12 is easier when cleaning the drain pipe 1. For this reason, by making the cleaning range of one drain pipe 10 with a cleaning mouth into the range from the branch pipe 12 of the drain pipe 10 with the cleaning mouth to the branch pipe 12 of the drain pipe 10 with the next cleaning mouth downstream. The drainage pipe 1 can be efficiently cleaned. Further, when the drain pipe 1 sandwiched between the drain pipes 10 with the cleaning port is damaged, only the drain pipe 1 can be removed for repair or replacement, and maintenance is easy.
